A virus is a pathogen that can cause an individual to develop an illness. A disease is a physical condition that causes the body to change its normal composition. A virus can cause a disease which in turn can cause someone to become sick.
The saying travel is good for the soul actually has some value. In recent years travel has been a difficult task. Now that the world is reopening, more and more people are looking forward to getting back out there.
Traveling has several positive effects on your mental health. Traveling has the ability to take you out of our daily routine and into new surroundings and experiences, and this can reset your body and mind.
Meningitis is an inflammation (swelling) of the protective membranes covering the brain and spinal cord. Usually, a bacterial or viral infection of the fluid surrounding the brain and spinal cord causes swelling. There are millions of meningitis cases worldwide, and some forms of meningitis are more serious than others.
History tells us that it takes more than vaccines to end a pandemic, this is still true. The science behind disease transmission, infection, and prevention can only get us so far. Ending a pandemic requires scientific advancement and social cooperation.
Vaccination efforts for smallpox began in 1796 when Edward Jenner observed that people who previously contracted cowpox were unaffected by smallpox. After observing this, he began to work on developing a vaccine.
Rabies is a virus that is caused by Lyssavirus. It spreads throughout the nervous system once infected, and ultimately reaches the brain in animals and humans. But, when it reaches the brain in animals, this is when the virus begins to multiply. Once that happens, the virus travels to the salivary glands, which is how rabies is spread through a bite.
Animals can contract rabies through the same way that humans do, through an infected bite by another animal. In the United States, rabies typically occurs in wild animals that are not domesticated. These animals include:
Contrary to popular belief, just because a person has had malaria once, does not necessarily mean they are protected from getting it again.
Being infected once with the disease does not make a person immune. This is one of the common myths surrounding malaria, according to Reuters. Malaria can resurface and infect a person for a second time. Even if an individual has grown up in an epidemic region, this doesn’t guarantee protection from the disease either.
Pregnant women should receive a dose of the tetanus, diphtheria and pertussis vaccine, also known as TDAP. This vaccine is critical to protecting the newborn from contracting pertussis (“Whooping Cough”). Because infants are at the highest risk of developing life-threatening complications from pertussis, vaccination of the mother during pregnancy is very important.
Anytime that you go traveling to an area that has sanitary practices that are different from what is commonplace to you at home, you are at risk for picking up travelers’ diarrhea. Even a climate change that is different from what you are used to can also make it more likely that you may contract it.
Travelers’ diarrhea is a disorder of the digestive tract, and it is caused by either bacteria, a virus, or a parasite in the local water or food that may be mishandled. It’s most prominent symptom is very watery and loose diarrhea. Some other symptoms include:
Rabies is an illness that many people fear contracting. But, human cases of rabies are rarely seen. That is, unless you get bit by a rabid animal. In that case, it is important to get treated as soon as you think you have been infected. Rabies is caused by a lyssavirus, which is a type of virus that causes encephalitis – an inflammation of the brain. According to the Centers for Disease Control and Prevention, approximately 59,000 people die annually from rabies.
Everyone knows flu season is usually during the cold months in fall and winter when most activities are held indoors. This shared air between people allows the flu virus to easily spread to others, causing more numerous cases of the flu to emerge.
If you forget to schedule your annual flu vaccination in the fall, you might think missed the opportunity to be protected for that current flu season. The good news is you can get the flu vaccine pretty much anytime you need it, so it’s never too late to shield yourself from the virus.
